Firing furnace and press furnace

Abstract

The invention relates to a firing furnace or press furnace for dental restoration parts, having a control device for the control of the furnace on the basis of at least one firing/press program; a display device, at least for displaying operating instructions based on symbolic representations; an input device, at least for selecting a firing/press program; wherein the control device is configured to be able to switch the furnace after selection of a control program to a security mode in which it displays one or several operating instructions and in which the input of firing or press parameters of the control program and/or the selection of a firing or press program is disabled.

The invention claimed is: 
     
       1. A firing furnace or press furnace for dental restorations, comprising:
 a control device for the control of the firing furnace or press furnace on a basis of at least one firing/press program; 
 a display device, at least for displaying operating instructions based on symbolic representations; 
 an input device, at least for selecting a firing/press program; 
 wherein the control device is configured to be able to switch the firing furnace or press furnace after selection of a control program to a security mode in which the display device displays one or several operating instructions and in which input of firing or press parameters of the control program and/or selection of a firing or press program is disabled, 
 wherein in the security mode, at least one of (i) an open furnace function, (ii) a close furnace function, and (iii) start of a selected firing/press program can be enabled. 
 
     
     
       2. The firing furnace or press furnace according to  claim 1 , characterized in that the firing furnace or press furnace comprises a programming mode, wherein the programming mode comprises options for programming and changing programs including changes to at least one program, reprogramming of at least one program, a change to at least a sequence of stored programs, a change to prioritization of the stored programs and/or authorization of users for selection of given programs can be produced, changed or deleted. 
     
     
       3. The firing furnace or press furnace according to  claim 1 , characterized in that the input device is integrated in the display device or coupled to it, and comprises a touch screen facilitating operation of the firing furnace or press furnace at least in the security mode. 
     
     
       4. The firing furnace or press furnace according to  claim 1 , characterized in that the firing furnace or press furnace can be transferred from a programming mode to the security mode upon actuation of one single control panel or any other single control function. 
     
     
       5. The firing furnace or press furnace according to  claim 1 , characterized in that the firing furnace or press furnace can be transferred from the security mode to a programming mode by entering a code or a hidden control function or via remote control. 
     
     
       6. The firing furnace or press furnace according  claim 1 , characterized in that in the security mode firing programs and/or press programs can be selected and executed depending on the design of the furnace as a firing furnace or press furnace. 
     
     
       7. The firing furnace or press furnace according to  claim 1 , characterized in that the input device and/or the display device comprises a field which is provided with Start or a corresponding symbol, wherein the Start field starts a preselected program in the security mode. 
     
     
       8. The firing furnace or press furnace according to  claim 1 , characterized in that the display device and/or the input device comprises a stop field or a corresponding function, as a symbol, which is active both in a programming mode and in the security mode and terminates the press program or firing program which has already been started. 
     
     
       9. The firing furnace or press furnace according to  claim 1 , characterized in that in the security mode, once a program has been started, a signal field and/or an acoustic signal is active when a press program or a firing program, depending on the type of firing furnace or press furnace, has been started and is running. 
     
     
       10. The firing furnace or press furnace according to  claim 1 , characterized in that at the end of a program in the security mode, the end of the program is signaled by an optical and/or acoustic signal and/or the firing furnace or press furnace enters into an energy saver mode automatically or manually. 
     
     
       11. The firing furnace or press furnace according to  claim 1 , characterized in that the display device and/or the input device comprises a field which is associated with programming and is designated by P, wherein the field associated with programming and designated by P when in the security mode, allows to select a program out of programs available to a user and, in a programming mode, facilitates to freely program programs, comprising to change, set up and delete programs. 
     
     
       12. The firing furnace or press furnace according to  claim 1 , characterized in that the display device and/or the input device comprises a Home button and/or a field for entering a code which is active and controllable both in a programming mode and in the security mode and which is used to reset the firing furnace or press furnace to an initial state in which free programming in the programming mode or free operation in the security mode is possible. 
     
     
       13. The firing furnace or press furnace according to  claim 1 , characterized in that the display device and/or input device comprises at least one symbol field for opening the firing furnace or press furnace and at least one symbol field for closing the firing furnace or press furnace, wherein the symbol fields for opening and closing the firing furnace or press furnace are active when no firing/press program is running. 
     
     
       14. The firing furnace or press furnace according to  claim 1 , characterized in that in addition to the security mode and a programming mode, a priority operating mode is selectable, by activating a selection field from the programming mode and/or by entering a code from the security mode in which a user can set further parameters, wherein setting further parameters comprises changing firing parameters and/or press parameters of programs temporarily, beyond functions of the security mode. 
     
     
       15. The firing furnace or press furnace according to  claim 1 , characterized in that a high security mode is selectable in which only one single firing/press program can be started and which can be left in the security mode, a priority operating mode and/or a programming mode by entering a code. 
     
     
       16. The firing furnace or press furnace according to  claim 9 , characterized in that the acoustic signal comprises a buzzing sound.
